Plain-English brief. Written for readers who work in a second language.
Key takeaways
- Attackers abuse legitimate platforms
- More than 25 platforms were observed
- Trust in services aids delivery
- Abuse affects multiple service types
What happened
The report comes from Cisco Talos. Cisco Talos observed abuse of more than 25 legitimate platforms over the past year. Attackers targeted collaboration services for delivery. Attackers targeted file-sharing services for delivery. Attackers targeted payment services for delivery. Attackers used other legitimate services for the same purpose.
Why it matters
Built-in trust in those platforms aids delivery for attackers. Legitimate infrastructure removes a common delivery barrier. Multiple service types extend the available attack paths. No single platform type limits the observed abuse.
What to do
- Verify allowed use of collaboration platforms for file transfer.
- Restrict access to file-sharing services by use case.
- Review payment service permissions for approved actions.
